Question

Find the perimeter of the adjoining figure *

​

Answer 1

Answer:

It's 14 cm or m ?

Perimeter of the Given

Figure : -

= Sum of Perimeter of both Semicircles /

Perimeter of a Circle Having Diameter 14 cm

+ 2 { Length along Horizontal Which is 21 m }

= As , We know Circle's Perimeter is 2 × π × r

( As , Diameter is 14 cm So , Radius is 7cm )

= [ 2 × 3.14 × 7 cm ] + { 2 × 21 m }

= { 14 × 3.14 cm } + 24 m

( Since , 1 m = 100 cm )

= 43.96 cm + 2400 cm

= 2443 . 96 cm

or , 24 . 4396 m
